2 Claims. 1

This invention relates to a trailer for raising and transporting agricultural implements along a road or from one place to another on a farm, and more particularly, for hauling a drag or toothed cultivator, a disk harrow or other implements which cannot be dragged or wheeled along Without damage or injury to roads and also for carrying a culipaclrer or earth roller while the trailer is coupled to and drawn by a tractor.

Another object of the invention is to provide a trailer for raising and transporting a drag or disk narrow, which can be readily coupled to the tractor draw bar by means of a hitch, by one man and provided with windlasses for attaching to a disk harrow and means for driving the windlasses manually or by power from the power take-off of the tractor, to raise the disk clear of the ground for transportation from one place to another, and with a derrick or crane having a swinging jib or boom by which a drag or toothed harrow or cultivator may be raised and mounted upon the wheeled frame of the trailer to be similarly transported, in addition to transporting other implements such as a culipacker or bar roller.

Another object of the invention is to provide a novel construction of wheeled trailer having means for raising and lowering the tractor hitch thereof to be coupled to the draw bar of the tractor by one man, in the form of a stand adapted to be raised to permit the trailer to travel on its wheels in connection with the tractor hitch or to be lowered, for raising the hitch to couple the same to the drawbar of the tractor and having means designed to be driven from the power take-on of the tractor for operating the windlasses or raising and lowering means which permits the harrow or wheeled disk cultivator and drag or tooth harrow to be raised from the ground or to be lowered for use.

Another object of the invention is to provide a simple and economical trailer construction which is supported by the tractor where it hitches to the draw bar thereof at the front, and sup ported by pneumatic tires at the rear, and provided with means whereby one man may pick up a four-section drag and double disc harrow with a minimum of eiiort, and to transport the same from one place to another on a farm or along roads, and also transport other implements in a .oonvenient and expeditious manner and avoid damage to roads and property.

Other objects and advantages reside in the details of construction and operation as more fully here nafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure l is a side elevation of a trailer constructed in accordance with the invention.

Figure 2 is a top plan view of the trailer.

Figure 3 is transverse sectional view taken on the line 33 of Figure 1.

Figure 4 is a longitudinal sectional view taken on the line 4-4 of Figure 2.

Figure 5 is a transverse vertical sectional view taken on the line 5-5 of Figure 1.

Figure 6 is a detailed fragmentary transverse sectional view taken on the line 5-6 of Figure 2, and

Figure 7 is an enlarged transverse vertical sectional view taken on the line 7 i of Figure 4.

Referring to the drawings in detail, the trailer of the present invention is shown as comprising a wheeled frame it, including parallel longitudinal fram members i approximately fifteen and a half feet in length or otherwise and connected by transverse reinforcing and connecting bars i2 to a width of about three feet and a half or otherwise and about three and a half feet off of the ground. The longitudinal frame members or bars i! are shown made up of upper and lower tubular members or channels I3 connected by vertical reinforcing plates or webs I d at suitable intervals, welded to the members 53 and between which the transverse tubular and horizontal reinforcing or connecting bars 12 extend and are fastened at their extremities. At other intervals, in lieu' of the transverse members i2, and between the same, windlasses are supported including transverse horizontal shafts i5 journalled in bearings 16 in certain of the plates it of the longitudinal members i! and projectin out from the sides thereof a considerable distance as well as spaced apart in parallelrelation longitudinally of the frame the distance between the disks of the double disk harrow represented in dotted lines at H, the disks of which are represented at D. These shafts form windlasses in connection with ropes 40 or cables I! which are attached to th shafts which may be tubular or otherwise, and are provided with hooks or other devices it at their extremities by which the cables i'i' may be looped around the frame of the harrow as indicated in the drawings, and the hooks i8, engaged with the depending ends of the cables to support the harrow and to raise and low-er the same with respect to the ground. As shown, four of such cables or lifting devices are mounted along the lengths of the shafts l5 and each is provided with a squared end IQ for the application of a crank for turning the same manually if desired. Also, each shaft is provided with a ratchet wheel 2 adapted to be engaged by a dog or pawl 2! for holding the shafts when turned, to support the harrow in an elevated position clear and off of the ground.

In order to support the trailer, oppositely inclined and vertical braces 22 connected by a cross-brace 23 are arranged near the rear ends of the frame members II, supporting an axle housing 24 at their lower ends, on the spindle ends of the axle 25 of which suitable transporting Wheels indicated as pneumatic tired Wheels 25 are journalled.

At the front, a stand 21 is provided vertically, the same being connected to inclined braces 28 and 29, the former extending outwardly in inclined positions or diverging downwardly from the side members II to a horizontal :bar 30 at the bottom and the latter or inclined brace 29 extending from the cross-member I2 centrally to a tractor hitch bar 3! connected to the bar 33 and. a rearwardly extending forwardly inclined brace 32 connected to the cross-member It in rear thereof. The hitch bar 3i extends forwardly 1 in a horizontal position and is provided with upper and lower apertured hitch members 33 and 34 designed to take a pin 35 for attaching or coupling the same to the tractor draw bar 36 suitably supported as indicated at 37 from the rear axle housing 38 of the tractor 33 having the usual tractor wheels 30. The stand 2I as shown in Figures 1 and 6, includes an upper section connected to the braces 28 and 29 and the hitch bar 3! at its lower end, and having telescoping therein by reason of the tubular construction of the stand section 2'1, a lower tubular section II having a supporting foot 32 to rest on the ground without penetrating the same. A cable 33 is connected to the upper end of the movable section II as indicated at 44 and extends downwardly through said section II and through a slot 45 in one side thereof at the inside where it passes under a pulley 46 after passing through an opening in the stand section 27 and then upwardly over a tubular or Windlass shaft 41 supported in bearing sleeves 4B and 49 horizontally supported in the braces 32 and a vertical brace 50 and at the brace 29 respectively. The forward end of the horizontal shaft 47 which also may be tubular, is designed for the application of a hand crank 5! whereby it may be turned in one direction to wind the cable 43 on the Windlass shaft 41 to lower the section 4| of the stand in supporting position, or to raise the same from engagement with the ground by turning the windlass in the opposite direction, in either position of which it may be held by means of a set screw 52 engaged through the bearing sleeve 49 and with the shaft 41. may be reinforced by webs or plates 53 at opposite sides in connection with the brace 29. The foot 42 is designed to be raised off of the ground when transporting the harrow or to be lowered, to support the trailer which is uncoupled from the tractor for coupling the latter to the harrow when the latter is lowered to the ground and detached from the trailer at the windlasses or cables IT by detaching the hooks I8 after the trailer has been lowered by the windlasses as will be readily apparent. Also, in addition to the gusset :plates 53, the bar 35 and braces 32 and 53 may be reinforced by gusset plates or webs 55 and 55 welded in position. In addition to manually turning the shafts I5 by means of hand cranks such as the hand crank 5| which may be applied to the squared ends of the shafts I5, the latter may be driven by power from the power take-off of the tractor indicated at 53 by a universal coupling 5!- connecting the power take-off shaft to an inclined shaft 53 and by a universal joint 59 connected to a longitudinally extending driven shaft 38 journalled in bearings ISI supported by the cross-members I Z, or otherwise suitably connected to the power take-off with a spring clutch Incidentally, the bearing sleeve 49 or otherwise as a safety element. The shaft 60 is suitably operatively connected to the shafts I5 as by means of suitable gears indicated in the form of worms at 62 engaging worm gears 63 on the shafts I5 to wind the cables I! on the windlass shafts I5 to raise and lower the harrow by power. In order to operatively connect the shafts I5 with the shaft 65, the worm gears or pinions 63 are slidably mounted or keyed on the shafts I5 as indicated at E6 and carried by grooved collars 55 adapted to be slid back and forth on the splines or keys of the shafts I5 by means of levers 66 having forks connected to the grooved collars and pivoted as at 57 on the frame III as to the cross-members I2, the levers extending between the plates I5 of the side members II so as to operate the shafts I5 independently or simultaneously by shifting the respective worm gears or pinions 63 into connection with the gears or worms G2 on the shaft 30.

At the rear of the trailer, a crane or derrick 68 is provided, the same having a vertical mast 69 rotatable in a sleeve bearing I3 and extending vertically and reinforced to the side members of the frame by webs or gusset plates II and I2 as shown more particularly in Figure 5 of the drawings, and offset outwardly approximately six inches from the side members II at one side of the frame III. The mast 59 is adapted to turn or swing in an arc of three hundred sixty degrees, that is a complete circle, and held from dropping by a suitable support, rib or collar I3 at the bottom and may be provided with an additional collar I I at the top to rest on the upper end of the sleeve I0 and turned thereon. The mast is provided with a swingable jib or boom I5 in the form of an arm extending horizontally and braced to the mast as indicated at I5. The free end of the jib or boom I5 carries a pulley II over which a cable I8 is trained, said cable carrying at its depending free end, a cleViS or hook or other similar device I9 for attaching the same to a drag or toothed harrow indicated generally at T by dotted lines in Figure l of the drawings. The cable then extends inwardly over the top of the jib or boom I5 and around a pulley 83 supported on said end, suitable bearings or brackets 8| being provided at the inner and outer ends of the boom to support the pulleys 7! and 80. The cable I8 then extends downwardly through an opening 82 at the inner end of the jib or boom and upper end of the mast 69, and downwardly through the latter and under a guide pulley 83 supported in a bearing bracket 84 at the lower end of the mast and sleeve, after which it is extended upwardly and rearwardly to wind around the single projecting end of a shaft 85 also journalled in the side members II of the frame III at corresponding longer or shorter plates I d near the rear end of the same. This shaft is provided with similar turning or winding means for the windlasses and pawl and ratchet mechanism as heretofore described in connection with the shafts I5, and gear shifting means, for operatively connecting the shaft 85 to the shaft 60 the same as in connection with the shafts I5, and similarly numbered.

Also provided at the rear end of the frame is a corresponding mounted transverse shaft 85, which like the shafts I5 and 85, is mounted in corresponding bearings in the frame members I I and provided with squared ends to take a crank as at I9 01' 5I for manually turning the same, except that the shaft 86 is not shown driven by the shaft 33 which has its rear bearing on the rear cross-member I2. However, the ends of the shaft 86 both project for taking cables 8! to form windlasses, and provided with hooks 88, to lift any other suitable farm implement such as a culipacker or bar roller and carry the same along on the trailer with the drag and disk harrow.

In the operation of the device, the hook, clevis or other connection 19 is attached to the toothed cultivator C and the windlass or shaft 85 is turned to wind the cable 13 thereon, while the jib or boom 75 is projecting outwardly as shown in the drawing to raise the drag T, until the drag or harrow is at the proper height above the frame It], after which the jib or boom is swung inwardly over the frame of the trailer and the shaft 85 turned in the reverse direction to lower the drag or harrow upon the frame. The trailer is then pulled over the double disk harrow H and the stand 2'! lowered to support the trailer. The shafts [5 are manually operated or power driven from the tractor through the medium of the shafts 56, 56 and 66 to wind the cables I! of the windlasses upon the shafts l5 after the cables are engaged with the frame of the harrow in the manner shown in Figure 1 of the drawings with the hooks l8 looped around the harrow frame and engaged with the cables below the shafts. By rotating the shafts and windlasses, the harrow is raised above the ground. Of course, it is to be understood that the trailer is coupled to the draw bar of the tractor by raising the front end of the trailer through the medium of the crank 51 by lowering the section 41 of the stand 2?. Then, when the trailer has been coupled and the harrow and drag raised in the manner described for support upon and suspension from the frame of the trailer, they may be transported around the farm or over roads to the place where it is desired to use same, without damage to property or injury to the roads. One man can couple the trailer to the tractor and also operate the device to raise a four-section or other sized drag or toothed cultivator and a double disk narrow with a minimum of effort so that the same can be transported from place to place and lowered for use, at which time, the trailer is uncoupled from the tractor and the latter used for operating the instruments over the soil.

While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.
